Submitted by admin on 19 October For this to happen, the gate pin of the TRIAC should receive a voltage greater than the threshold gate voltage and should also get a current that is greater than gate trigger current.
This problem can be solved by providing a resistance in series for the capacitance to discharge. Complete Technical Details can be found in the datasheet present at the end of this page. The gate threshold voltage of the BT is also very less so can be driven by digital circuits. It can be avoided by using a snubber circuit.
Looks like a suitable substitute to me. I added the links in the first message. This commutation is normally done by reducing the load current forced commutation less than the holding current.
Meanwhile, in the MOC datasheet it does not mention the maximum current, only the surge current. This way the Load can not only be switched but also the output coltage can be controlled by using PWM signals for fast switching. I have a schematic which uses a triac, for example a BT So if you looking to switch of control dim, speed control an AC load which consumes less than 6A with a digital device like microcontroller or microprocessor then BT might be the right for you.

When controlling the output AC voltage for dimmer or speed control applications a Zero crossing method is always recommended to daatasheet used. We need special type of circuit called commutation circuit to turn of the SCR again.
Please confirm if I am right. Other than controlling through switch the BT can also be controlled through a microcontroller or a microprocessor. There is chance of backward current when the TRIAC is switching inductive loads, so an alternate discharge path has to datsheet provided for the load to drain the inrush current.

Latching current looks a bit higher for thebut that’s about it. You bh136 read this article if you want to know more about the switching modes.
I searched again for datasheet using the exact part number of the two components and it seems that the gate current is the same for both components. Please have a look at the attached schematic this is a schematic for a soldering station What parameters from the datasheet we should take into consideration, when we are searching for a equivalent triac?
